Eh?  I'm confused by your statement "I don't think it's worth our time writing bindings".  How else
will we get scriptability?

How do you call a function if it isn't defined?  If you have native functions that you want to
reflect into a particular scripting language, you have to tell it that those functions exist.

This requires features of a full component system, afaik.  For example, being able to understand
interfaces at run-time.

I'll do that.  isugamedev/lib/scribe
